Hair examination has become recognized as a robust method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by encapsulating biomarkers within the strands of hair as it grows. When gathered near the scalp, hair can reveal a detection period of up to approximately three months for alcohol and drugs. It is straightforward to gather, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches containing roughly 200 hair strands (equivalent to the thickness of a #2 pencil) from the scalp yields 100mg, which is optimal for screening and confirmation. For tests like EtG, additional tests, or those exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar amount of body hair can be used. References to head hair mean scalp hair exclusively, while body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step includes confirming that the sample was sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary rapid check for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive screen must be verified to be valid in legal settings. Samples that are tentatively positive in Screening necessitate a subsequent confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the original sample and readied for Extraction. This stage involves extracting drugs from hair at a lower concentration than found in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.
Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and meets the accreditation to ISO / IEC 17025 standards.

Note: Although frequently termed "hair follicle tests", the analysis targets the hair strand rather than the follicle underneath the scalp
